Research interests:
Dr. Valentine's broad research interest is in ecosystem ecology, biogeochemistry, and element cycling in northern ecosystems. His past research focused on the role of soils in forests, grasslands, and wetlands in generating or consuming trace gasses, especially carbon dioxide and methane, that influence Earth's climate. His recent research has focused on the effects of wildfire and moisture stress on soil respiration and carbon balance. He teaches courses in soils, nutrient cycling, sustainability, environmental ethics, and environmental decision making based on integrating the major foundations of natural resource management: natural sciences, economics, human values and behaviors, ethics, and policy.Current research programs:
